Bitcoin scarcity explained
What is Bitcoin halving?
Bitcoin halving is a programmed event that reduces the block reward paid to miners by 50%. It is built into Bitcoin's rules and is one of the main reasons Bitcoin has a predictable supply schedule.
A halving happens every 210,000 blocks. Because Bitcoin targets an average block time of about 10 minutes, that works out to roughly every four years, but the exact date and time can move as real block production speeds up or slows down.
Miners still compete to add new blocks to the blockchain after a halving, but they receive fewer newly issued bitcoins for each block. Transaction fees may also be part of miner revenue, but the new block subsidy is the part that gets cut in half.
This matters for Bitcoin scarcity because the pace of new BTC issuance slows after each halving while the maximum supply remains capped at 21 million BTC. Over time, each halving adds a smaller amount of new Bitcoin to circulation.
The block reward is not the same thing as the Bitcoin price. Halving changes the supply schedule, but price still depends on demand, liquidity, market sentiment, regulation, macro conditions, and many other factors.
A halving does not guarantee a price increase. This page is an educational countdown and supply explainer, not financial advice or a trading signal.

How can halvings affect the market?
Historically, halvings have attracted attention because they reduce new miner rewards and lower the rate of new BTC issuance. Some market participants watch halvings as part of Bitcoin's long-term supply story.
Market reactions can vary widely. Volatility, demand, liquidity, regulation, mining economics, broader risk appetite, and market sentiment can all matter before and after a halving.
